Virtual HP41 and Virtual HP-IL



#2

Is there a virtual HP41 that goes withChristoph Giesselinks Virtual HP-IL? Alas no, AFAIK. Or is there someone at it? Should I do it? (There is a 'IL add on' for the Nonpareil-HP41, but does it talk with ILPer/ILSope/etc.?)

Well, the HP-71B (and Emu71/Win) is the better IL controller but I feel more comfortable with the HP41.

Emu41 by J.F. Garnier works with the virtual HP-IL. It's a console (DOS) based program, but it quite a capable emulator.

Yes but it's limited to it's own virtual devices inside emu41.

Since MS-DOS does not have a TCP-IP stack, emu41 cannot establish a socket with Christoph virtual devices.

One solution will be to share alternatively a LIF drive between the two simulated world (emu41 & emu71).

A second solution requires 2 PIL-Box with a setup like this ...

emu41 -> VCOM over USB -> PIL-Box-1 -> HP-IL -> PIL-Box-2 -> VCOM over USB -> ILPer -> other virtual devices

There are IP stacks for DOS. Google for packet driver.

Another option would be to add IP support to EMU41 and/or Nonpareil. Both are open source.

You are right.

But what I meant was that Microsoft did not include a generic IP stack with a standard API that would have been included on all MS-DOS machine.

Thanks for everybody who replied. Seems a tricky thing. BTW, TCPIP did work on DOS in some way as "we" used the HP200LX for eMail and such things quite well, with modem or via IrDA mobiles.

Ciao.....Mike
